Transforming existing buildings is key to making your building portfolio and industrial facilities fit for the future.
A condition analysis serves as the basis for optimal decision-making.

With the help of a detailed condition analysis of building envelopes and technical systems, we identify possible measures to safeguard existing buildings.
Based on this, we calculate your potential savings.
These are systematically and cost-effectively presented in a concrete action plan. An investment plan for short-, medium-, and long-term measures provides planning and cost certainty for the financial planning of SMEs, developers, operators, and users.
In the industrial sector, we use pinch analysis as a tool with the goal of optimally combining a minimal total amount of investment and energy costs using the various cooling and heating flows.

​Value-preserving measures​

Investments in technical systems (HVAC/R systems) and in the building envelope are usually directly related to high investment costs.
In the event of a failure, the building services systems must be replaced as quickly as possible to ensure uninterrupted operations. Only those who identify such replacement investments early on have a chance of increasing a building's energy efficiency. A condition analysis by SADRIJAJ uncovers potential for energy improvements and any structural and technical risks in a timely manner. By cleverly combining packages of measures, synergies can be utilized and ancillary costs can be significantly reduced. This creates a sophisticated building strategy that can be incorporated into the medium- and long-term financial planning of SMEs, developers, operators, and users.

​Recognition of potentials

During an initial inspection, the most important aspects of the building envelope, technical systems, and processes are examined from an energy perspective. Thanks to the systematic evaluation of the recorded data, SADRIJAJ can assess the potential in individual areas and develop initial suggestions for improvement. This provides an ideal basis for defining the next steps in the long-term process of increasing energy efficiency.

Suggestions for measures

Every single measure, whether value-preserving or efficiency-enhancing, relating to the building envelope, heating, cooling, ventilation, plumbing, and electrical systems, is documented and described. To provide a sound basis for decision-making, the resulting investment costs and expected savings are calculated as benchmarks. In a final step, the measures are prioritized and divided into short-, medium-, and long-term packages. This creates the foundation for sound financial planning for the resulting investments.

Pinch analysis

Pinch analysis can significantly improve a manufacturing company's thermal energy requirements. To achieve this, SADRIJAJ records the thermal energy flows of the process plants or adjacent systems such as infrastructure facilities. The goal of pinch analysis is to minimize the heating and cooling requirements of complex processes through an optimal heat exchanger network. The savings potential depends on the process type and often ranges between 10 and 30%.

Energy profile with measuring points

Energy monitoring enables a meaningful comparison of key performance indicators from different locations within a real estate portfolio or a production facility. For example, reliable statements can be made about energy consumption per location or the efficiency of individual systems. An energy profile for each location and a measurement concept for identifying missing measuring points form the basis for a consistent starting point at all locations. SADRIJAJ supports the entire process – from clarifying needs to implementation and quality assurance – thus ensuring the successful implementation of energy monitoring.
